Detailed Description
The core of the application is to provide a command line recording method, a system, a device and a readable storage medium, which are used for providing a command line recording mode for effectively tracking problems.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the continuous development of information technology, data is gradually valued as a precious resource, and how to quickly process data resources and obtain expected results becomes one of the key problems of resource-to-asset transition. Data are generated by various activities of people in work and life, useful information can be obtained by collecting the data and analyzing and processing the data, and the conversion from resources to assets is realized, so that the rapid development of big data and high-performance calculation is catalyzed. Data storage, one of the core elements of data resources, has also been in the period of rapid development. The traditional network storage system adopts a centralized storage server to store all data, the storage server becomes the bottleneck of the system performance, is also the focus of reliability and safety, and cannot meet the requirement of large-scale storage application. The distributed network storage system adopts an expandable system structure, not only improves the reliability, the availability and the access efficiency of the system, but also is easy to expand, thereby being accepted by more and more enterprise units. Distributed storage systems typically consist of 1 to N nodes to provide high performance, mass data storage.
In the use process of the distributed storage, as the server system allows multiple points to log in and execute operations at the same time, some operations may cause some faults, some operations may affect projects of other users, and the historical command line tracing tool carried by the operating system cannot completely and accurately record the command line operations of all users. Because the operation of each user by the command line tool of the operating system is cached in the local of the terminal, the tool can refresh the local cache into the log file only when the user terminal normally exits, but the data content stored in the command line tool is too little, and an effective basis cannot be provided for problem tracking. The present application therefore provides a method for command line recording that solves the above-mentioned problems.
Referring to fig. 1, fig. 1 is a flowchart illustrating a command line recording method according to an embodiment of the present disclosure.
The method specifically comprises the following steps:
s101: receiving a command line sent by a terminal;
the command line is a common man-machine interaction mode, which is provided by a command line operating system, and is an input and output interface of the computer operating system, as opposed to a graphical interface. Specifically, the command line displays only characters and does not display graphics on the screen or a window of the computer. Command lines were the mainstream before no graphical interface appeared, and now, after computer performance was greatly improved, command lines were used less and less. However, because the format of the command line is flexible and simple to implement, commands like find files have more filtering capabilities than find based on graphical interfaces and are not complex to use, and thus are still used in some areas. Such as dos commands and linux commands, are still used by a wide range of users after windows and linux have graphical interfaces.
Preferably, when command lines sent by a plurality of terminals are received, the parameter information of each command line is recorded in the system log file in an additional recording mode, so that the condition of command line coverage is avoided, the command lines sent by each terminal can be ensured to be recorded in the system log file, and an effective basis is provided for history tracing and problem location.
S102: when detecting the execution action of the command line, acquiring the parameter information of the command line;
the parameter information of the command line mentioned here includes the content of the command line, the execution time of the command line, the IP address of the executor of the command line and the directory where the command line is located, which can not provide effective basis for history tracing and problem location in the prior art, and if all login users log in the server with the same user name, who executes the command line can not be distinguished; by acquiring and recording the content of the command line, the execution time of the command line, the IP address of the executor of the command line and the directory where the command line is located, the method greatly improves the possibility of effectively tracing the command line of the terminal.
Optionally, the parameter information of the acquisition command line mentioned here may specifically be:
and acquiring the parameter information of the command line through a system command line recording tool history.
S103: and recording the parameter information of the command line into a system log file.
Because the system log is not lost, command line traceability is guaranteed for subsequent viewing.
Preferably, when the parameter information acquisition command is received, the steps shown in fig. 2 can be further executed, which will be described below with reference to fig. 2.
Referring to fig. 2, fig. 2 is a flowchart of another command line recording method according to an embodiment of the present application, which specifically includes the following steps:
s201: when a parameter information acquisition command is received, determining a target command line and a target position according to the parameter information acquisition command;
s202: and reading the parameter information of the target command line in the system log file, and outputting the parameter information of the target command line to a target position.
In the prior art, a method for centralized management of user command line input and system log information of all nodes is provided, wherein a log server periodically scans user history information and system log information on a management node, however, the method has the characteristics of dependence on a network, continuous consumption of system resources, dependence on the history command line recording condition of each managed node and no real-time recording, if the log server fails, the command line information during the failure cannot be collected, and if all logged-in users log in the server with the same user name, the scheme cannot distinguish who executes the command line.
In the method, all users logged on the server node, command lines executed by the ip and directories where the executed command lines are located are recorded on the server node in real time. Because it is a local record, it is not dependent on the network; no system resources are consumed when no command line is entered; command lines entered via a display, keyboard, direct connection to the server node are also within the scope of the record. The recorded command line information is stored in a system log according to the execution time, and the system log is more targeted to problem and fault troubleshooting.
Based on the technical scheme, the command line recording method provided by the application receives a command line sent by a terminal through a server node, obtains the parameter information of the command line when the execution action of the command line is detected, and then records the parameter information of the command line into a system log file.
